Description

Technical Field

[0001] The present application relates to the field of fire detection, and in particular to a positioning mechanism for fire detection. Background Art

[0002] Fire detection usually refers to the regular inspection and testing of fire-fighting equipment and systems in buildings or facilities to ensure their ability to work properly and protect personnel safety in the event of a fire. Existing fire water systems include fire pumps, fire pools or water tanks, fire pipe networks, etc., which are used to provide sufficient water pressure and water volume for fire extinguishing and water spraying. Fire water systems need to be inspected and maintained regularly.

[0003] During the inspection and maintenance process, since some fire protection pipes are installed on the top of the building, people need to use a lift to lift the pipes close to the height during inspection. However, the lifting height of the lift is limited. When disassembling and repairing the inspected pipes, people need to manually lift the pipes for disassembly and installation. The lifting platform at the height of the lift has a limited range of movement. People are restricted by height and space when operating, which makes it inconvenient to inspect the fire protection pipes and reduces the overall work efficiency of fire protection inspections.

[0004] With respect to the above-mentioned related technologies, the inventor believes that when using a lift to inspect high-altitude fire-fighting pipes, there is a defect that it is inconvenient to disassemble and assemble the pipes. Therefore, a positioning mechanism for fire-fighting inspection is proposed to solve the above-mentioned problem. Utility Model Content

[0009] Preferably, the bottom of one side of the second bevel gear moves close to the outer surface of the first bevel gear, and the first bevel gear and the second bevel gear are meshed with each other.
